在字符串中添加单引号 [英] Add single quotes to a string

问题描述

我尝试在字符串中添加单引号，但看不到该怎么做.例如，我想用"ABC"代替ABC.

I try to add single quotes to a string but don't see how to do it. For instance I would like to replace ABC by 'ABC'.

我玩过 paste ， cat ， print ，但看不到该怎么做.

I have played with paste, cat, print but don't see how to do it.

有解决方案吗?

谢谢，文森特

推荐答案

只需使用粘贴:

R> paste("'", "ABC", "'", sep="")
[1] "'ABC'"

或新品种

R> paste0("'", "ABC", "'")
[1] "'ABC'"
